A statement from Stevenage has confirmed that midfielder Robin Shroot has been placed on the transfer list.
The 25-year-old has appeared nine times for the League One club this season, but it is believed that he will no longer be considered for selection.
A spokesman told the club's official website: "This is the second time Robin has requested a move in 12 months.
"We don't want anyone in the squad who doesn't want to be here, so this time we've agreed to put him on the list and if our terms are met, he can move on."
Shroot started his professional career with Staines Town.
